Bug Description

The version of audacity in trusty seems to be missing LADSPA support: under Effects, I see only 29 plugins listed. Downgrading to version 2.0.3-1 (from raring/saucy), I see the expected list of 277 plugins.

[Impact]
LADSPA plug-ins provided by Debian packages (which install plug-ins into /usr/lib/ladspa/) are not found by Audacity by default.

Hi,
Audacity 2.0.5 was released in Debian without ffmpeg support because it has not been fully ported to the libav9 library. Apparently, noone stepped forward to do the work so it was necessary to do this to allow the libav 9 transition to complete. See Debian bug #692809.
It would be great if someone could create some patches to forward upstream. One patch is available (attached) from the Debian bug.

The attachment "Partial fix" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

I don't think Audacity's ffmpeg support has anything to do with this bug, because it shows up with a version that I custom-compiled with ffmpeg support as well. A workaround is to symbolically link the /usr/lib/ladspa folder into /usr/share/audacity:

sudo ln -s /usr/lib/ladspa /usr/share/audacity/ladspa

...or if you compiled your own version and installed it with the /usr/local prefix:

Thanks Chris. I think you are right. Audacity seems to be looking in the wrong place for the ladspa plugin. A Debian bug reporter has found that it is looking in /usr/lib/x86_64-linux-gnu/ladspa instead of /usr/lib/ladspa.

Ross

Would it be terribly difficult to make the search directory configurable?
It seems like sub-par design to hard code the path. In my opinion, the
ideal would be to have a configurable list of search paths. That way, if
the plugins are stored in multiple locations, we can still see them all. Of
course, this fix is more on the Audacity side of things.

Also, a quick search of the source from github actually shows it searching
in "/usr/local/lib/ladspa", set into the path list in
"src/effects/ladspa/LoadLadspa.cpp". It would be simple to just set this to
the correct path and be done with it.
